Question

Malachy rolls a fair dice 168 times.

How many times would Malachy expect to roll a number greater than 5?

Answer 1

28 times

Explanation:

On a fair die, the probability of rolling a 6, the only number greater than 5, is 1/6. So in 168 rolls of this die, Malachy can expect a 6 on 1/6 × 168, or 28 times.
